General Garrett Turbo on Evo

So the differences in power is purely boost. If I keep the car beyond its warranty and pcp agreement I'll be unleashing the extra horses!

If you mean the difference between the Evo Abarth and other Evos, then it is the turbos that have a different turbine (internal) design. This gives the Abarth a significant increase in boost at a higher RPM. This makes it less suitable for pottering about, but deliver more power at sustained full throttle. The programming of the valve timings will be significantly different with a bias to power also. I don't have any Evo engines, so I haven't researched the fine detail of the parts, but a quick look suggests that apart from turbos, there are few or no significant differences between Evo FIRE turbo engine internals apart from turbos as valve timing can simply be adjusted in the ECU for different specs.

Without the benefit of MultiAir, previous Abarth T-Jets, Bravo 150 and high spec Alfas had higher lift (I call them Abarth) cams as well as the larger turbos to give them an extra edge. Again, this had the effect of raising the power band up the rev range. Good power can be had from 1500RPM in a 120 T-Jet, but subjectively, I would say it is 3000RPM in a 150 or Abarth T-Jet. It's something to think about if you only very rarely want to cane it.

Wow, you really know your stuff! :worship:
 
I guess the world of variable vein turbos is still too expensive for the little Fiat. Still a very impressive little engine though.
 
Up to how many hp can the Garrett GT turbo on the Punto EVO Multiair 135 take?
 
does anyone know about the upgraded turbo for it word on the grape vine is a g28 garret will fit with an adapter but before going balls deep into i need to find out 100% if i does fit
